This thread began with a question asking how to help a PWP get dressed in spite of the difficulties caused by parkinson's.
One CareGiver with problems like yours uses empty plastic bread bags to help get the socks on her husband's legs. She cuts open the closed end of the bag and puts it inside the sock. Then she pulls on the sock with the bag inside it. The bag makes the sock slide on more easily. When the sock is up, she pulls the bag out the top and slides it back down outside the leg and off.
Maybe something along these lines would work for you, too.
PS the plastic bag idea seem good.
